IRON;

Application led April 4,` 1925. Serial No. 20,794. K,

The yinvention relates ftoimprovements in an iron of the type adapted toreceive -a solid fuel to be consumed therein during the use of theironto generate heat.

It is -an object of the invention to provide escaping heated gases fromthe top. of the iron are controlled bya suitable damper and aredeflected so asto be always maintained out of contact with the handsofthe user.

Among other objects. the invention embodies an iron by means of whichthe solid fuel undergoing combustiontherein Acannot escape during theruse'of the iron 'through' the airopenings;` to provide an iron withVanr improved form of base to facilitate the com-. bustion ofAthefuel;,to provide an iron with., a base lto conduct Athe heat t'o thevgpoint of the iron where the highest temperature is desired.

In the drawingsi 'Figure' 1 is a -topplanfview of the iron assembled,

Fig. 2 is a vertical longitudinal sectional view of the iron,

Fig. 3 is a transverse vertical sectional view7 Fig. 4 is a fragmentaryvertical sectional view showing in detail a portion of the draftproducing structure,y

Fig. 5 is a horizontal sectional view clearly illustrating the bottom ofthe iron, and

Fig. 6 is a bottom plan view of the iron cover.

Referring now more particularly to the drawings wherein like referencecharacters indicate corresponding parts, the numeral l designates thebody of the iron having the i base 2 which is of the usual shape. Thebase and the side Walls formingy the body are( preferably made from anintegral casting of metal, the interior of the body being hollow toprovide the opening 3 therein.l

The iron disclosed in this application is intended to burn av solid fuelsuch las. chars coal, coke, or any of the other well known Theinventiony furthermore aims to prof vide Van liron-'of thischaracter inwhich the fuels useful for this purpose. Such'fe'l is placed Within thefuel receiving openingf in the interior of thefbody.' Means must beprovided to cause a constant and proper consumpt'ion of this fuelinOrder-fthat sufli'cient heatbe generated to properlyheatfthe base ofthe iron. I provide at'theforward part of the iron at one side anopeningl preferably semi-circular and leading into-anair feeding anddeflect'ing tubular member 5for` directing the yair downwardly towardthe base of the iron. This member has anove'rhanging shoulder 6extending` well within the opening inthe iron forthe purpose ofkpreventing. fuel from jarringV out ofthe* opening 4 duringthereciprocationy ofthe iron. Acontrolling valve 7 is pivotedinto thekiron by means of.' which the diameter of the air feeding opening'fmayfbe.varied at will. n

The opposite side of the iron :near the rear vthereof is provided withasimilar opening 8. This opening leads to' the tubular vair "passageway9' of the same:y structure as 4-here'tof fore described indiscus'singfthe vtubularairv passageway 5. The overhanging yporoutstanding ledge 97 isalso providedfto prevent the jarring Yof fuelthrough 'this opening when the iron is in use.V The rotatable closure,capY 10 I'is ,employe/d forv .controllingH this opening 'by means 'of'which the" draft can be varied. It will be understood that the tubularair conducting passages 5 and 9 are formed by casting integrally withthe sides of the wall inwardly and downwardly extending walls being, ofcourse, spaced from the bottom of the iron body. Itwill be understoodthat by arranging the air feeding openings in this manner, that is oneat the forward part of the iron at one side and the other at the rear ofthe ironat the opposite side there is a constant circulation of airthroughthe iron during its reciprocation. v

The-base of the iron is furthermore pro` in the base of the ironfurthermore constispring 21 riveted `to this strap so that when l5 thetop is to be applied it is only necessary tomove inwardly the fingermember 19 and to then insertthe forward tip 15 of the slot into thesocket 16, By yreleasing the finger member 19 the detent then dropsunder an 20 inwardlypextending catch 22 and the top is then detachablyheld in place. It will be seen that the top is provided with a pair of"circular openings 22 disposedon each side thereof. These openings arecontrolled by a` 25 plate 23 secured to apin 24C extending through thetop, which pin at its outer end receives a lever 25;. The plate isprovided With openings 26 of the same configuration as the openings 22in the top of the iron,

30 and by rotating the handle 25 the openings` Vin the plate. and thetop may be brought into or out of alignment, thereby controlling thedraft in the iron. A spring 29 mounted on the supporting pin for thecontrolling plate urgessaid plate upwardly so that it frictionallyretains itselflin any position of adjustment.- A i It is apparent thattheissuing gases from the iron should not come in contact with the 40hand .of the user grasping the handle 30 connected with the handlecarrying strap 20.

To this end a false cover 31 is provided, the same being secured to thetop of the iron at its center by means of rivets 32 while the ends ofthe false cover are raised or spaced from the cover for detlectnig thegases outwardly at the side of the iron.

It will thus be seen that when the iron is in use the removable top canbe taken from the base of the iron by shifting the finger plug 19. Anydesired solid fuel can then lbe placed in the iron. The damperscontrolling the openings 4 and 8 in the side of the iron are regulatedso that the required amount of air passes through the fuel in the ironduring its reciprocation. The damper in the top of the iron isalsoregulated' by the operation of the handle "25 serving to control thedischarge ofexhaust gases from the iron and thesel gases pass out underthe dei-lector rplate separated at each of its f'sides from the irontop. The variousclosures for theV gas and gas openings can be set topermitany regulated quantities of air or gas to pass therethrough inthis way affording a veryV positive -control for the combustion of thefuel in the iron.

Having thus described my invention, what Iclaimfis:

In a sad iron, in combination a base and a body having Walls, said bodybeing adapted to receive a solid fuel,`a` tubular air conducting ductleading from each side wall of the body and extending inwardly anddownwardly toward the base thereof, the lower Wall of the ductconstituting an overhanging ledge for` preventing the ldischarge of fuelthrough said duct, and valves for controlling said air openings.

In testimony whereof afiiX my signature.
